Why?

The angle β = 40° between the sling leg (cięgno zawiesia) and the vertical falls within the range up to 45°, rated at 9000 kg on the tag. The 6000 kg rating applies above 45° up to 60°, so it is not the maximum permitted mass here. A smaller angle does not permit exceeding the stated 9000 kg rating.
